One… Two… Many…
Phase transitions describe dramatic changes in properties of a macroscopic system - like the transition from a liquid to a gas. Starting from individual ultracold atoms, physicists were able to observe the emergence of such a transition with an increasing number of particles. (1) One. Two. Three. Many. The whole cosmos can be explained by…

Building…
Scientists have discovered a way to control the growth of twisting, microscopic spirals of materials just one atom thick. The continuously twisting stacks of two-dimensional materials built by a team create new properties that scientists can exploit to study quantum physics on the nanoscale. (1) 3D from 2D. 4D from 3D. 5D from 4D. And…

Knowing thy name…
Physicists surprised to find that in specially coated tubes, the more viscous a liquid is, the faster it flows. (1) Water. Dripping fast. Honey. Dripping slow. Things changing. Only because of things changing. Honey. Dripping fast. Water. Dripping slow. Ask yourself. Would you ever ask why? Oh, wise man... (What is your name?)

Having a fever. Having a fever?
Measuring the temperature of objects at a nanometer-scale has been a long challenge, especially in living biological samples, because of the lack of precise and reliable nanothermometers. An international team of researchers has realized a quantum technology to probe temperature on a nanometer-scale, and have observed a 'fever' in tiny nematode worms under pharmacological treatment.…

Refuting the refutations of the Wigner-Neumann interpretation in quantum mechanics
Refuting the refutations of the Wigner-Neumann interpretation in quantum mechanics Spyridon Kakos1 1 phD, National Technical University of Athens Athens, Greece, August 2024 Abstract One of the most controversial interpretations in quantum mechanics is the Wigner-Neumann interpretation, according to which the superstitions collapse only when a conscious observer observes the quantum system. In general, there…
